Application led May 5, 1921. Serial No. 467,192.

T0 all u1/wm t may concern. l y

Be it known that I, WILHELM Moena, a citizen of Germany, residing at Cannstatt, Germany, have invented certain new and uselfmprovements in Work Stands, of which the following is a specification.

My inventionrefers to the repairing of umbrellas and more especially to a device for use in carrying out work of this kind. In repairing umbrella frames, more especially in repairing the rods forming part thereof, it has hitherto been necessary, either to take the entire frame to pieces, or at least to remove the plates, as also the steel or wooden points of the umbrella. lin the latter case, repair work is very troublesome and requires a great deal of time because, during the work, the umbrella must be held with one hand.

The object of my invention is a novel workstand in which during the work of repairs, the umbrella is firmly held, at the same time providing a support for the rods and rendering the removal of the plates and points unnecessary. ln this manner the new implement will cut down the time required for repairs by one half.

Tn the drawings accompanying this speci- Iication and forming part thereof a device embodying my invention is illustrated by way of example. In the drawings--h Fig. 1 is a side elevation,

Fig. 2 a vertical section,

Fig. 3 a cross section on the line A--B of Fig. 2, drawn to a larger scale.

Referring to the drawings two tables b and c are fitted to a column a. The upper table c carries in its center a chuck d, this chuck being fixed to the table and tapering upwardly; it contains three suitably shaped chuck-jaws e. Between these chuck-jaws are fitted the springs m which tend to force these jaws apart.

The lower part of the chuck-jaws e isk connected to a bushing f, which has a strong spring g pressing against it. This bushing and the spring are contained inside tube a which may be said to form a prolongation of the column a. Tube a is mounted upon the upper cylindrical collar of the column a and may be clamped thereto at any desired height by means of the set screw o.

The bushing f is provided with a longitudinal slot which engages a lever k rooking about a horizontal pivot on the tube n in such a manner as to allow the stick of an umbrella to pass through the center of the tube a. l

To the outer end of lever 7L there is attached a tension rodi which is `adjustable inside a head piece grand which may be,

locked in position by means yof a screw The head p is attached to a pedal 7c, the arrangement being such that when the pedal h is pressed down, the head 79 and the rod -i are raised7 the lever h being thereby moved in counterclockwise direction until thebushing f guided inside the tube a is pushed downward against the pressure of a spring g, thus exposing the chuck-jaws e to the action of the springs m and allowing the bushing t to slide downward.

The manner of operation of the workstand is indicated in Fig. 2 of the accompanying drawing.

Theumbrella rod to be repaired is cut loose from the covering of the umbrella. Thereupon the wire-ring holding the forks of the rods to the slide is opened and the umbrella covering may now be turned over towards the point of the umbrella, without difficulty. By pressing down the pedal Ze the chuck-jaws e are moved apart and the point of the umbrella stick, which in Fig. 2 is represented broken-off, may be inserted between the chuck-jaws e. When the pedal l: is released., the umbrella stick will be held firmly between the chuck-jaws.

The umbrella rods at first take up the position shown on the right in Fig. 2. Now, the wire holding the rods together in the crown in loosened, whereby all rods are released and spread over the two tables b and c as indicated on the left-hand half of Fig, 2.

W'hilst the faulty rod is being repaired. all other parts of the umbrella are arranged in the new implement in a clear, orderly manner and in such a position as to facilitate in an extraordinary degree the re-assembling yof the umbrella. Moreover the umbrella occupies little space whilst in the iixture and does not obstruct other work.

After the necessary repairs have been effected or after one or two rods, etc. have been replaced, the umbrella may be put together again on the new implement, as will be understood without further explanation. During all this work, the plate or point of the umbrella need no longer be removed, such as has hitherto been the case.

A particular advantage of the new implement is that the height of the stand may be adjust-ed by means of the set screws 0 and Q', to suit umbrellas of different sizes and to be handy to the person using the imlement.

The tables b and c may also be used for depositing tools, utensils, etc.

I claim:

l. In a device of the kind described in combination, a hollow column, an automatic y clamping chuck supported on said column,

means comprising a pedal lever for opening said chuck and a` pair of tables carried, one above the other, by said column.

2, In a device of the kind described in 1,4se,see

tuated chuck on top of said column, a pedal lever projecting through a longitudinal slit in said column, a table surrounding the 4*top end of said column and another table dis= posed at some distance below said lirst table.

In testimony whereof I affix my signature.
